Passiflora kapiriensis is a new Guianese species in the series Laurifoliae of subgenus Passiflora, found near Saint-Georges-de-l'Oyapock. The filaments of the fourth corona row are 1 cm long and oriented to the androgynophore, which is reminiscent of P. acuminata, P. cerasina, P. fissurosa, P. killipiana and P. nitida. It differs from these close relatives by the combination of subequal first and second rows of filaments, a very short hypanthium, very long petioles, with medial nectary glands, and much larger leaves.
